Q

When a cell performs phagocytosis, what is the vesicle called?

PH level

Temperature

Necessary Cofactors (vitamins, minerals)

30
Q

What happens to wrongly programmed proteasome?

Parts of the proteasome?

A

Cause disease
Misfolded proteins accumulate and impede function of other proteins

2 caps and a middle peice

31
Q

Peroxisomes are found?

Why named?

A

Liver, gallbladder

Has peroxide

32
Q

Name of sugar combustion in mitochondria?

A

KREBS cycle, or citric acid cycle

33
Q

When sugar combustion happens without O2 in cytoplasm?
How many ATP?

Type of reaction with O2?
How many ATP?

A
